More efficient engines using sustainable aviation fuels combined with optimised flight paths and reduced taxiing time. Only use digital tickets.

Sometimes we don’t need the cream and toothbrush; sometimes a pair of socks is sufficient. Being able to customize the amenity kits in advance reduces waste.
